5.9 Model LTD-04
5.9.1 Assembly
The LTD-04 model consists of two components, the sensor itself and a special air purge. These two components
are supplied separately in an unassembled state. Therefore, before installation, the LTD-04 model must be
assembled as follows:
1. Make sure that the supplied mounting bracket - or an adequate mounting fixture - is attached to the sensor
with the mounting nut.
2. There is a sticker with an arrow on the sensor body. For correct assembly, now screw the air purge onto
the sensor only until the arrowhead is in line with the connection fitting for the air injection.
Figure 5-25: Assembly of the Air Purge
Note
The air purge is specially designed for the LTD-04 model. This air purge is not identical with the air purge
according to section 13.2.9
Note
The sensor has been calibrated at the factory with the air purge installed. Deviations from the above assembly
instructions may result in incorrect measurements.
Note
Each air purge is uniquely assigned to the sensor. The air purge must not be interchanged even within the
LTD-04 model series.
